Correct Answer: D

Rationale: The major characteristic of a cardiac malformation associated with left-to-right shunting is increased blood flow to the lungs. This increased flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a typical characteristic of this condition. Severe growth retardation (Choice B) is not directly associated with left-to-right shunting. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions involving chronic hypoxia.

Correct Answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

Correct Answer: A

Rationale: The most appropriate statement by the nurse in this scenario is to inquire about the family's daily routine. This question allows the nurse to gather information about the family dynamics, the care routine for the infant post-surgery, feeding schedules, and potential stressors. It opens the conversation in a non-intrusive manner and helps the nurse assess the family's situation to provide appropriate support. Choices B, C, and D do not address the situation effectively. Asking about the daily routine is crucial for the nurse to understand the family's needs and offer targeted assistance.

Correct Answer: A

Rationale: The correct answer is to monitor liver function tests regularly. Methotrexate, commonly used in JIA, can be hepatotoxic. Regular monitoring of liver function tests is crucial to detect any signs of liver damage early. While encouraging regular exercise (choice B) is generally beneficial for overall health, it is not directly related to methotrexate therapy. Providing high-calorie snacks (choice C) is not a necessary consideration in this context and can be misleading. Encouraging frequent handwashing (choice D) is important for infection control but is not specifically related to the medication methotrexate.

Correct Answer: B

Rationale: Encouraging fluid intake is essential in the discharge instructions for a child who has had a tonsillectomy. It helps keep the throat moist, aids in preventing dehydration, and promotes healing. Gargling with salt water is not typically recommended after a tonsillectomy as it may irritate the surgical site. Providing the child with hard candy is not advisable as it can irritate the throat and potentially cause harm. Applying heat to the neck is also not recommended post-tonsillectomy as it can increase swelling and discomfort in the surgical area.
